The Shichibukai

The Shichibukai, otherwise known as the Seven Warlords of the sea, are seven well known pirates who have allied themselves with the World Government.

Who are the Shichibukai?
The Shichibukai is a group of seven pirates who work for the World Government. Although they work under them, they do not care about or respect the World Government. Sometimes the Shichibukai are even regarded to be 'no different than other pirates' by some members of the marines.

The Shichibukai don't like to work with each other, preffering to stay on their own. (Such as Fudo) However, some such as Ryumen and Reaper have worked together in the past and seem to be okay with working with each other.

Members
The members of the Shichibukai are varied, from extreme calmness, to madness, to constantly angry. They are as follows:

Corral - Corral has only been seen twice. Once during the meeting of the Shichibukai, and then during the Straw Hats execution. He appears to have some kind of history with Vincent Bastion (Talon)

"Sword-Tooth" Ryumen - Possibly the most active member, Ryumen is a man of few words and even less forgiveness. He also has links with Vincent Bastion, being defeated by him just after he joined.

Korten - As of the most recent chapter, Korten is the only Shichibukai not seen. His voice was heard during a meeting with Micheal Hawkes, and he is known to have defeated three of the Ten Kings; anything else is unknown.

Toshiro Fudo - A man who swears in every sentence, Fudo has been an important Shichibukai, single-handely taking down Dragon Claw and even defeating Gouki Riosho in battle.

Reaper - Also a member of the Ten Kings of the Gods, Reaper is a skeleton figure with links to Gouki Riosho, another member of the Ten Kings.

Mai Hioro - Mai is the only female member of the Shichibukai, and all that is known is her looks and the fact she has a unique sword.
